administrative region of the People's Republic of China, Japan, New Zealand,
South Africa or the United States.


Ahlstrom Corporation's Board of Directors have today signed a new demerger plan
related to Coated Specialties, Ahlstrom's Label and Processing business in
Brazil, and cancelled the previous Coated Specialties demerger plan. Under the
signed demerger plan, all the assets and liabilities contained in the Ahlstrom
Group, that belong to the Coated Specialties business in Brazil, will be
transferred to Munksjö Oyj through a partial demerger. The demerger is part of
the process through which Ahlstrom's Label and Processing business and Munksjö
AB will be combined.

The signing of the new demerger plan and cancellation of the previous one were
needed since Ahlstrom and Munksjö will not be able to receive all relevant
regulatory approvals before May 27, 2013, when the demerger decision made by
Ahlstrom's Extraordinary General Meeting of the Shareholders expires. As
announced before, Ahlstrom expects to complete the demerger of the Label and
Processing business in Brazil during the second half of 2013. Ahlstrom will
later this month publish a separate invitation to a new Extraordinary
Shareholders' Meeting, which is required to obtain approval for the new Coated
Specialties demerger plan.

The new complete Coated Specialties demerger plan is attached to this Stock
Exchange Release and it contains information on the demerger consideration to
Ahlstrom's shareholders, the planned time for execution of the demerger, the
division of the demerging company's assets and liabilities to the recipient
company and the conditions for the execution of the demerger.

Munksjö Oyj, as the recipient company in the partial demergers, will publish a
prospectus concerning the shares offered in the demerger approximately one week
before Ahlstrom's Extraordinary General Meeting for Shareholders.

The demerger plan, signed on September 11, 2012 related to Ahlstrom's Label and
Processing business in Europe, is pending, for example, an approval by the
European Commission competition authorities. This decision is expected during
the coming weeks. Consequently, the execution of this demerger is expected to
take place on or before May 27, 2013.

The two demergers form a step in the execution of the transaction between
Ahlstrom and EQT concerning the combination of Ahlstrom's Label and Processing
business and Munksjö AB that was announced on August 28, 2012.
